Problem with power managment in EMC2

[ad_Wolf]

Hi! I think that I have a problem: when I run EMC2, power of my step-motors is turning off. After this Z-axis is going down and tool regards to the table =(

P.S. Sorry for my bad english!

What kind of computer are you using?
What drives are you using?

I use step-motor drives. After EMC2 is loaded, I must turn power on. There is a problem: power already turned on in my drives, they are working, and Z-drive retain a spindle. After EMC2 loaded, he off the power in the drives, and Z-drive turn down the spindle.

What brand of stepper motor drives are you using?
What kind of computer are you using?
What breakout board are you using?

Why do you have power turned on to your drives before powering up EMC2????

It sounds like you don't have the drive enable signal setup correctly in EMC2.

Ок, brand -- motionking.
Computer -- Amd celeron kakoj-to tam, motherboard-Via, 256 mb ram.
Signal setup working correctly. I can show you the standart_pinout.hal file.
This is especially the realization of drivers.

Obviously something is not correct or you would not have asked the question. I am just trying to get enough information to allow us to help diagnose the problem.

I understand. How can I turn off this option? I don't need this, but I don't know how turn off power managment im EMC2. Power of drivers turnings off or on manually.

I guess I am confused because there isn't any automatic power management in EMC2.

There are signals that can be implemented to enable drives. There are signals that can be implemented to tell that an estop switch has been activated. There are signals that can be implemented to turn a spindle on or off. There are signals that can be implemented to tell that an axis has reached end of travel (limit). These are all things that you would have to set up in your ".hal" file.

Maybe it would be helpful if you posted your ini file and your hal file.

Please try to answer all of my questions. It is hard enough to diagnose problems when you can see and check the wiring directly, it is even harder when you can't see and check the wiring directly.

Generally, I wouldn't want to have my drives powered up and hooked to my computer without having my control software running first. I don't want the computer sending any signals to the parallel port except when told to by my control software.

Ok, now back to my questions, why do you have power turned on to your drives before starting up EMC2?

If you start EMC2 first and then turn your drives on does it still not work?

Which model MotionKing driver are you using?

Are you using a breakout board? If yes, what brand and model? Does it have or require a separate power source for opto-isolation?

There is an enable/disable pin on at least some of the motionking drivers. Do you have anything connected to the enable pin?

It also looks like you have a whole bunch of signals in your hal file that have nothing to do with a standard stepper system. A bunch of stuff that appears more like having to do with servo systems.
